It's because unlike with american cards you have to confirm the transaction on the card reader while it shows you the amount (with either a pin or signature in some cases). After you confirmed it the transaction cannot be changed, i.e. the tip cannot be added. So the american way of tipping does not work with foreign cards.
I don't understand why credit cards are secured so badly in the states.
Here you can't adjust a charge after it has been confirmed (plus you usually have to enter a pin whan swiping the card if the amount is over a certain threshold).
Kind of related: when my family went to the US for vacation and we ate at some restaurant, the waitress came with the bill, my dad said something like "make it $x". When she sait to just write in the tip on the bill and my dad told her that won't work she insisted that thats how it always works (which tbf it probably does for american customers).
Sure enough when we checked the card statement later on they just took out the original amount, not the tip writen in.
Whenever this gets discussed, a bunch of status quo warriors pop out of wells to say "Trump is worse." Like, no shit.
Yes, but it still needs to be said every time because it would be detremental to leave even the tiniest chance for this (valid) critique of Biden to help Trump in the presidential election.
That is why I think it's inportant to point out the obvious (Trump is way worse) because it is obvious to most but might not be to some and it would be a massive Issue if those people could take this discourse as reason not to vote for Biden in november.
Weigh some things you know the exact weight of like 1L of water or your phone (you can google most phones weights, without the case and only if you dont have a screen protector of course).
I had the same issue at home but realized my scale was jus off most of the time.
A while ago a collective in germany used a software to merge the faces of two people into one photo and used it on their passport.
On one hand the idea was to evade facial-recognition software which uses the passports photo.
On the other to use the passport to smuggle refugees into europe by plane.
I am not sure the software was based on Machine learning but would strongly suspect it.
You might be on to something, it might have been the lizzard people!
